ERNEST E. HUMPI-IREY, or LINCOLN, NEBRASKA ADJUSTABLE BABY-JUMPER.

To all whom it may concern:

Be it known that I, ERNEST E. H'UMPHREY, a citizen of the United States,residing at Lincoln, in the county of Lancaster and State of Nebraska,have invented an Improved Adjustable Baby-Jumper, of which the followingis a specification sufliciently clear to enable those skilled in the artto which it appertains to make and use the same.

Its object is he production of a baby jumper which is adaptable to ababy of any weight and in which the jump of a baby of any weight isconveniently and safely capable of a wide variation and of a form notlikely to mar furniture or woodwork, adapted to be used in comparativelyrestricted space, and which can be economically made and placed on themarket at a comparatively low price. These purposes are attained in myinvention by certain novel construction and combination of parts andmaterials which will be hereinafter described and claimed.

My invention is illustrated in the accompanying drawings, which form apart of this specification and in which drawings similar characters ofreference refer to similar parts.

Figure 1, represents a vertical elevation of my device. Fig. 2,represents a crossseotional view of my springs on the line (L 277 C 2'77I prefer the following forms of construction though I reserve all rightsof variation therefrom within its general purpose and conception.

I make my invention with two spiral steel springs preferably thoughother suitable metal may be used. These springs a and b as shown in Fig.1 of my drawing, I make of different sizes, the smaller spring b beingadapted to freely slide within the larger spring a. I make the spiralportion of the larger spring a shorter than the same portion of thesmaller spring Z) so that the spiral portion of the smaller spring 7)normally projects slightly beyond the ends of the spiral portion of thelarger spring a. I form each end of the larger spring, a into alongitudinal, elongated loop 0. I position the loops 0 of the largerspring a at one side of the line of the central opening in the largespring a to allow free independent Specification of Letters Patent.

extension of the small spring b. I form each end of the small spring 6into a small, longitudinally extending loop, CZ. I connect the upperloops 0 and d by a metal 8, which is lettered m in drawing, the upperportion of which 8, I form into a hook adapted for attaching to aneyelet or other top support. The lower loops, 0 and (Z I securelyshackle together by the section of open link chain, c by attaching oneend of the chain to each loop respectively, to permit free andindependent motion of each spiral spring.

I make a carrier connector, f of the general form of a letter 8, howeverwith the lower portion thereof closed and the upper portion forming ahook shaped member adapted to snugly engage and be interchangeable inthe opening in any link of the chain c I make my carrier supports, geach preferably from a single strip of strong denim, which foradditional strength and wearing qualities I fold together and sew with acentral, longitudinal seam. I use a plurality of carrier supports whichI separate, approximately midway their length by a metal spreader, hwhich I make of suitable metal wire, portions of which spreader, I bentat approximately an angle of forty five degrees and at uniform distancesapart on same to form rests, h upon which I attach the carrier supportsso as to directly oppose the horizontal strain of the supports on thespreader. I attach the upper end of each carrier support to the metal 8,f, the central part, of each support to its rest, 71. on the spreader itso that the spreader is suspended horizontally between same, and Iattach the lower end of each carrier support, at uniform distances apartto the main portion of the baby carrier, 7' so that it is suspendedhorizontally thereby. I make the carrier also of strong denim, of aplurality of thicknesses, sewed together to give strength anddurability, in two portions. The main portion of the carrier I make inthe form of a wide waist band for a baby, j and adapted to hold the babyand furnish support for its body. I make a second portion of thecarrier, is in the form of a narrower band having a central part, Zformed into a padded roll to act as a spreader and furnish a comfortableundersupport for the baby. I attach each end of the part is to oppositeside band portion, j so as to depend therefrom as shown in the drawing.

The utility of my construction Will be at once apparent.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

In a device of the character described, in combination, two spiralsprings, said springs being made one larger than the other, the smallerspring being adapted to freely slide within the larger spring, thespiral portion of the smaller spring being made slightly longer than thespiral portion of the larger spring, each end of each spring terminatingin a longitudinally extending loop, the loops on the ends of the largerspring being positioned at one side of the central opening of thespring, a metal 8, the loops on one end of each spring being attachedtogether by the lower, portion of the S, a chain shackle, said shacklebeing composed of open links and having one of its ends attached to thelower loop on the small sewed, a support spreader, said spreader beingmade of suitable wire in the general form of a continuous square buthaving its corners angled at forty five degrees from its sides, and acarrier, said carrier composed of fabric folded and sewed lengthwiseforming a wide Waist band, and an under support depending therefrom andhaving a padded roll midway its length.

In testimony whereof, I have signed my name to this specification in thepresence of two subscribing witnesses.
